Biology presentation

2. What is a Food Chain?
A food chain is the path by which energy passes from one living thing to another.

3. What’s in a Food Chain?
Producers
Consumers
Decomposers

4. Producers make their own food
Also called autotrophs and get energy from the sun
Producers are on the bottom of the food chain

5. Consumers
Consumers hunt, gather, and store food because they cannot make their own.

6. Three Types of Consumers
Herbivores
Carnivores
Omnivores

7. Herbivores Animals who eat plants such as: grasshoppers rabbits
squirrels
deer
pandas

8. Carnivores Animals who only eat other animals such as: tigers lions
hawks
wolves
cougars

9. Animals who eat both plants and animals such as:
Omnivores
Animals who eat both plants and animals such as:
humans
bears

10. Decomposers
Microorganisms that are able to break down large molecules into smaller parts
Decomposers return the nutrients that are in a living thing to the soil

11. Food Chains
A food chain is a simplified way to look at the energy that passes from producers to consumers.

12. Predator- An animal that captures and eats other animals
Predator & Prey
Predator- An animal that captures and eats other animals
Prey- The animal that is captured and eaten

13. Several food chains linked together
What is a Food Web?
A more realistic way of looking at the relationship of plants and animals in an environment
Several food chains linked together
A predator from one food chain may be linked to the prey of another food chain
